Foot Drop: What It Means When Your Foot Won’t Lift Properly

The Nerve, Muscle & Joint Health Newsletter
Understanding Your Condition
If you’ve noticed that your foot drags when you walk, or that you have to lift your knee unusually high to clear your foot off the ground, you may be experiencing a condition called foot drop. It’s not a disease in itself — it’s a symptom that signals a problem with the nerves or muscles that control the front of your foot and ankle.
Foot drop occurs when the muscles that lift the front of the foot (a motion called dorsiflexion) become weak or stop working altogether. This is most often caused by damage to the peroneal nerve — the nerve that runs along the outside of the knee and controls the muscles responsible for lifting your foot. When this nerve is compressed, injured, or affected by disease, the result is a characteristic walking pattern where the foot slaps the ground or drags with each step.
Common causes include:
- Compression of the peroneal nerve at the knee (from prolonged crossing of the legs, a cast, or a knee injury)
- A herniated disc in the lower back compressing the L4 or L5 nerve root
- Stroke, tumor, or spinal cord conditions affecting motor control
- Diabetic neuropathy affecting the peripheral nerves of the lower leg
- Hip or knee replacement complications affecting nearby nerve structures
Foot drop can also present with numbness or tingling on the top of the foot or the outer lower leg. In some cases, it comes on gradually; in others, it appears suddenly. Regardless of how it begins, the cause must be identified to guide the right treatment.
At Hands-On EMG, we use Nerve Testing (EMG/NCS) to determine exactly where the nerve dysfunction is occurring — whether at the peroneal nerve itself, at the lumbar nerve root, or somewhere along the pathway. This distinction is critical because treatment for a compressed peroneal nerve at the knee is very different from treatment for a lumbar disc problem. Our testing gives your doctor the specific information needed to move forward with confidence.

Safe Exercises to Support Foot and Ankle Function
If you have foot drop or weakness in the lower leg, the following exercises may help maintain strength and mobility while you are working with your care team. Always move gently and speak with your provider before starting. Stop immediately if symptoms worsen.

1. Seated Ankle Dorsiflexion Practice
Sit in a chair with your feet flat on the floor. Try to lift the front of your affected foot as high as you can without moving your knee. Hold 3–5 seconds, lower slowly. Repeat 10–15 times. Even partial movement helps maintain nerve–muscle connection and slows atrophy.

2. Calf Raises
Stand near a wall for balance support. Rise up on your toes slowly, hold 2 seconds, lower back down. Repeat 15 times. Strengthens the calf and supports overall lower leg function.

3. Resistance Band Dorsiflexion
Sit on the floor with your leg extended. Loop a light resistance band around the top of your foot and anchor the other end to a fixed object in front of you. Pull your foot back toward your shin against the band’s resistance. Hold 3 seconds, return slowly. Repeat 10 times.

4. Towel Toe Scrunches
Place a small towel on the floor and use your toes to scrunch it toward you. Repeat 10–15 times per foot. Activates intrinsic foot muscles and improves fine motor control at the toes.
Helpful Tips
- Wear an ankle-foot orthosis (AFO) brace if recommended by your provider — it holds the foot in a lifted position and significantly reduces fall risk
- Keep pathways at home clear and use good lighting — tripping hazards are a serious risk with foot drop
- Avoid sitting with your legs crossed for extended periods — this can compress the peroneal nerve at the knee
Did You Know?
Foot drop is not always caused by a problem in the leg. A compressed nerve root in the lower back can produce weakness that is felt only in the foot, with no back pain at all. Nerve testing identifies exactly where along the pathway the problem exists — making it possible to target treatment at the true source rather than the symptom.
